Nontechnical Abstract: The University of Washington Molecular Engineering Materials Center (UW MEM-C) addresses fundamental problems in materials research that push the frontiers of science, accelerate the development of future advanced technologies, and address challenges of broad national and societal importance. MEM-C's research activities stress innovation in the design, discovery, and application of complex electronic and photonic inorganic materials with low dimensionality. MEM-C also spearheads education, training, and outreach programs to prepare tomorrow's leaders in science and technology, with signature programs focusing on promotion of (re)entry of veterans into science/technology/engineering/mathematics (STEM) career tracks, and early recruitment/mentorship of students to STEM from underrepresented/underserved regional high schools. Additional activities include REU/RET/REM programs, regional K-20 outreach, regional partnerships for public engagement, and interdisciplinary curriculum development. MEM-C further strengthens ties between UW and industrial, international, and National Laboratory partners through sponsored internships and collaborations. MEM-C shared facilities provide lasting infrastructure that promotes the activities of the Center as well as of the broader campus and regional materials science communities.Technical Abstract: MEM-C's research involves two interdisciplinary research groups (IRGs): IRG-1: Defects in Nanostructures addresses the scientific challenge of engineering unprecedented physical properties into inorganic nanostructures by controlling defect formation and doping, and exploits these emergent properties to develop new technologies ranging from laser cooling to solar concentration; IRG-2: Layered Quantum Materials creates and studies new forms of quantum matter in atomically layered materials, emphasizing phase transitions in these materials, with potentially disruptive impact on energy and information technologies. Both IRGs integrate materials innovations with theory/computation at the interface of materials science, chemistry, physics, and engineering to identify and explore fundamentally new physical phenomena and to advance these scientific frontiers toward new applications. A competitive seed program supports high-risk high-reward projects in emerging areas. These activities are developing the materials underpinnings of future advanced technologies and simultaneously providing interdisciplinary education and training of the nation's future leaders in science and technology. Participants in the Center include 15 senior investigators, 5 postdoctoral associates, and 14 graduate students from 5 departments and 1 National Laboratory.

非技术摘要：华盛顿大学分子工程材料中心（UW MEM-C）致力于解决材料研究中的基本问题，推动科学前沿，加速未来先进技术的发展，并应对广泛的国家和社会重要性的挑战。MEM-C的研究活动强调在低维度复杂电子和光子无机材料的设计，发现和应用方面的创新。MEM-C还带头教育，培训和推广计划，以培养未来的科学和技术领导者，重点是促进退伍军人（重新）进入科学/技术/工程/数学（STEM）职业轨道，并从代表性不足/服务不足的地区高中早期招募/指导学生到STEM。其他活动包括REU/RET/REM计划，区域K-20外展，公众参与的区域伙伴关系和跨学科课程开发。MEM-C通过赞助的实习和合作进一步加强了UW与工业，国际和国家实验室合作伙伴之间的联系。MEM-C共享设施提供了持久的基础设施，促进了中心以及更广泛的校园和区域材料科学社区的活动。技术摘要：MEM-C的研究涉及两个跨学科研究小组（IRG）：IRG-1：纳米结构中的缺陷通过控制缺陷的形成和掺杂，解决了将前所未有的物理性质工程化到无机纳米结构中的科学挑战，IRG-2：分层量子材料在原子分层材料中创造和研究新形式的量子物质，强调这些材料中的相变，对能源和信息技术具有潜在的破坏性影响。这两个IRG都将材料创新与材料科学，化学，物理和工程界面的理论/计算相结合，以识别和探索全新的物理现象，并将这些科学前沿推向新的应用。一个有竞争力的种子计划支持新兴领域的高风险高回报项目。这些活动正在开发未来先进技术的材料基础，同时提供跨学科教育和培训国家未来的科学和技术领导人。该中心的参与者包括来自5个部门和1个国家实验室的15名高级研究员，5名博士后助理和14名研究生。
